A convenient, well-made solenoid used for investigating the magnetic field of a coil and for the current balance experiment.

  • The clear acrylic former and the 3-9/16 in. (90 mm) diameter allow items placed inside the coil to be easily seen
  • 5 tappings give easy access to windings of 100, 200, 300, 400, and 500 turns by simply moving 1 plug between the 5 red binding posts
  • The coil has a total resistance of 20, or 4 per 100 windings, and can carry up to 1.5A of current in a single 100-turn segment, allowing a 6V DC power source to be used (and up to 12V for the fill 500 turns)
  • All 5 segments are connected in series and the same current flows through all segments that are included in the circuit
  • For continuous use, the current should not exceed 1A
  • When the current is used intermittently (less than 1 minute at a time), it can go up to 1.5A
  • Current should never exceed 1.5A


  • Coil dimensions: 1-9/16 in. (4 cm) L x 3-9/16 (9 cm) dia.
  • Overall dimensions: 7-7/8 in. (20 cm) D x 4-3/4 in. (12 cm) W x 4-5/16 in. (11 cm) H
  • Total turns: 500
  • Total coil resistance (500 turns): 20
  • Maximum current: 1.5A (through 1 segment)
  • Includes activity guide
